Configuration

During the client configuration bootstrapping stage, subscribe to telemetry events like follows:

builder.telemetry(new TelemetrySubscriber() {
    @Override
    public void handle(final TelemetryEvent event) {
        logger.info("Received telemetry event: {}", event.name());
    }

    /**
     * Only subscribe to the events you want to receive
     */
    @Override
    public boolean supports(final String name) {
        return asList("job.selected", "job.created").contains(name);
    }
});
